Despite being known for her Perfect 10 bikini body, Bo Derek shuns regimented workouts in favor of open-water, horseback riding and caring for her 110-acre ranch in Santa Ynez, California, according to Examiner.

While shoveling horse manure, hauling bags of food to feed her horses and dogs and doing chores around a sprawling ranch is hardly glamorous, it’s a strenuous work that burns calories and requires plenty of strength.

“I get credit on one hand for not having had a facelift, and then on the other hand it’s, ‘Oh my God, why doesn’t she do something?'” Derek joked (see video). “So you’re just torn.”

Bo, who was married for 22 years to director John Derek before he died of heart disease in 1998 at the age of 71, has been dating actor John Corbett since 2002.

Bo and Corbett, 54 (who played Aidan Shaw on Sex and the City), live together on her California ranch, but have no plans to marry or have children.

Bo said she was immediately attracted to the dashing, 6-foot-5 Corbett when they first met in 2002. “It was love at first sight,” said Derek. “I was crazy about him from that moment. He’s charming and funny.”
